F BRIDGEEORT, GONNECTIL'CUT. A CORPORATION OF NEW SEAMING MACHINE.

Application filed October 25, 1923. Serial No. 670,682.

This invention relates generally to seaming machines for uniting containers and covers and has more particularly reference to a machine for acting upon a number of containers and covers at the saine time in which is employed a seaming tool having a spiral seaming surface and is an improvement upon Patents Nos. 1,121,894 of Dec. se, i914 and 1,400,796 @e Dec. 2o. 192i.

Fig. 18 is a detail view of the seaming means and work-holder showing' the seeming means about to begin the seaining operation.

The operation to be performed by the machine of this invention can best be understood by considering Fig. 18 Where 1 indicates a container and 2 is a cover or bottom to be seamed to the container. 3 indicates the stationary chuck of a suitable work-holding means and 1 is a spiral seaming element for uniting the cover and container, said seaming element having a continuous spiral groove that gradually becomes wider and shallower so that the general outline of the seaming tool is conical. By rotation of the parts and lengthwise displacement of the container and seaming tool, the'bottom and container are united. While to limit all the features of this invention to a machine capable of carrying out this operation is far from the intention, it will, nevertheless, be understood that the machine has been designed more particularly for the purpose of uniting a container and a cover in the manner described.

In accordance with the form of the invention herein disclosed, a plurality'of workholding means are provided on a rotatable turret which latter likewise carries a plurality of seaming tools so that a constant stream of containers and covers may be acted upon, the seaining operation being performed simultaneously on a number of pieces of work.

Referring first to the sheets of drawings containing Figs. 1, 3 and 12, 5 is a power shaftY having fast and loose pulleys 6 and Vprovided with a pinion 7 driving spur-gear 8 mounted fast on main shaft 9 carried by suitable bearings 10 and supporting, loosely, a turret 11 mounted on roller bearings 12. Keyed to shaft 9 is a pinion 13 meshing with gear 14E on auxiliary shaft 15 which latter carries a pinion 16 meshing with internal gear 17 on the turret whereby a revolving motion is imparted to said turret. Shaft 15 also carries a sprocket gear 18 that drives shaft 19 (Fig. 6) by means of sprocket chain 2O and sprocket 21. Shaft 19 drives the body infced mechanism in a manner to be subsequently described. The cover infeed mechanism is also driven from pinion 13 through idler 22 and gear 23 in a way to be described later. The turret (Fig. 8) carries a plurality of body-supporting pockets 2st and a plurality of cover-supporting pocklll ets (Fig 14) in alinement with each other and with suitable work-holding means consisting here of stationary chuck 26 and movable chuck 27; and, intermediate these pockets and nearer the center of the turret (Figs. 3 and 12) are spindles 28 carrying seaming tools 4. inasmuch as the several workiolding means are alike as are also the several seaminp' tools, only one ot each will be described. lt will be-observed, however, that the seaming tools are arranged in a circular group and that the work-holders are likewise arranged in a circular group outside the seaming tools and in staggered relation thereto so that one seaming tool serves tor two work-holders.

Referring particularly to Figs. 3 and 12, a flange ot turret 11 carries a sleeve 29 in which spindle 28 is slidingly mounted. At the other side ot seaming tool 4 is an auf;- iliary spindle 30 connected to spindle 28, as by coupling 31, and mounted to slide in sleeve 32 carried by another flange ot turret 11. Main shat't 9 carries a gear 33 that meshes with a pinion 34 on each spindle 28 whereby, due to a diderence in speed ot' the main shaft and the turret, rotation is imparted to the several spindles and seaming tools. Suitable means are provided for reciprocating the seaming tools and the spindles thereof consisting, in this instance, of the following: Carried at one end of each spindle is a yoke 35 having arcuate bearing members 36 and provided with a cam roll 37 One of the flanges ot turret 11 is provided with tour rods 38 (Figs. 7 and 12) that carry guide members 39 and that are connected by braces 40. @ne bearing member 36 of each ot two adjacent yokes slides on theV same guide member 39 and the two bearing members 36 ot each yoke 35 slide on guides 39 ot dinerent rods 33. Springs 41, extending between yoke 35 and brace 40, normally urges said yoke to the lett, in Fig. 12, and holds cam roller 37 against the camsurtace ot stationary cam 42 (Fig. 3). It will now be understood that rotation of the main shaft and revolution ot the turret causes each seeming tool to be rotated and to be reciprocated. To adjust spindle 23 to take upV lost mot-ion, there is keyed to reduced portion 43 (Figs. 12 and 13) member 44 that is provided with a filling block 45 extending into one of the teeth of tooth member 46 threaded on portion 43.

Each ot the plurality ot work-holding` means is construc-ted as follows: Figs. 3, 10, 11, 14, 15 and 16). Chuck 26 is stationary.7 in the sense that it has no longitudinal motion but a rotating motion is imparted to it in the present instance by means ot pinion 47 (Figs. 3 and 14) that meshes with corresponding pinion 43 (Figs. 3 and l2) mounted loosely on sleeve 32, said pinion 4o deriving its motion from spindle 28 by pi and slot connection 49. It will be observed. hat pins 49 are Jast in pinion 48 and are slidingly engaged in slots 5() ot head 51 secured to a reduced portion ot' auxiliary spindle 30 whereby the spindle is 'tree to slide but will, at the same time impart its rota-tion to gear 43 which does not slide. In its detailed construction, the so-called stationary chuck is as Jfollows: (Figs. 10, 11 and 14). Secured to a. A[lange ot turret 11 as by means ot bolts 52 passing through slots 53, is ay bearing 54 carrying sleeve 55. Sleeve 55 extends into an eloi'igated opening 56 ot the turret so as to permit radial adjustment ot bearing 54 to thereby make the machine available tor different sizes of cans. Seated in sleeve 55 a spindle 57 provided at one end with chuck iead or pedestal 58 and at a point in rear or" sleeve 55 with a filling block 58 that extends into enlarged portion 59 of bearing 54. Filling block 58 is provided with a stem 60 extending transversely out through bearing 54 and a spring 61 tends to keep filling block 53 out ot the enlarged or eccentric portion 59 ot' bearing 54. The object ot this construction is to permit the spindle to have a slightly yielding or rocking motion when the seaming tool passes over the longitudinal seam of the Vcan to compensate tor the entra thickness ot metal at that point. 62 is an end thrust bearing against which spindle 57 abuts. The movable chuck 27 is here constructed as tollows (Figs. 1, 3, 7, 14, 15 and 16) Carried by turret 11 is bracket 63 adjustably secured in position by mea-ns of bolts 64 passing through elongated slots 65. 66 is a sleeve bearing also adjustably secured to turret 11 in a manner similar to that employed in connection with plate 63. Sleeve bearing 66 extends through bracket 63 and through elongated opening 67 in turret 11 so that the center of the movable chuck can be adjusted to correspond to theadjustment of the stationary chuck when working on different sir/ies of Sleeve 66 is provided at its outer end with a head 69 between which and the turret a spring 70 is interposed, said spring normally urging said sleeve to the lett in 14. The head is provided with a cam roll El engaging stationary cam Z2 (Figs. 1, 3, 4 and 5) and with a guide roller 7 3 engag' plementary to l racket 63. At its other end said sleeve is provided with a crosshead Z4 connected to spindle 75, the latter' housed within the sleeve. its a consequence, said spindle follows the reciprocation of the sleeve. Carried by the spindle is a spring seated plunger or chuck head 76. This plunger is adjustable by means ot slotand bolt connection 7? (Figs. 14 and 16).

lt will now be understood that upon actuation ot the parts and can 1 and cover 2 being placed in the turret pockets, the movable ig bracket 63 which latter is comchuck moves toward the right (Figs. 1, 3 and 14.) thereby clamping the worlc and causing it to rotate. Seaming tool a also rotates and moves lengthwise in accordance with the lead of-the spiral seaming surface thereby uniting the can and bottom. As will be seen from Figs. 8 and 10, the turret has spaces for eight cans but has only four seaming tools, one seaming tool serving for two adjacent work-holders. As will also be seen from Figs. 8 and la., the turret is provided with openings 7S through which the seaming tool extends. Allthis, of course, takes place while the turret is revolving so that a num- V ber of cans and bottoms are acted upon simultaneously.

The can bodies may be fed by hand but `preferably automatic means are provided for feeding the bodies into the turret. 1n the present instance, these means talre the following form (Figs. 1, 2. 6, 7, 8 and 1'?) Bodies 1 travel down an inclined chute 79 and are received in the pocltets of a dial SO which delivers them to successive pockets of the turret. Dial 8O is mounted on shaft 81, (Figs. 6, 8 and 17) carrying gear 82 which latter meshes with pinion 8.3 on shaft 19.

rlhe covers or bottoms may be Vfed into the machine by hand but preferably automatic means are provided for feeding` said covers into the pockets of the turret, these means in the present instance taking the following form: Associated with inclined dial 10-l are fingers 1&4 which convey a cover and turn it edgewise into guide 145 (Figs. S and 9). From guide 145 the cover passes into groove Q5 (Fig. of one of the pockets of the turret where it is then associated with a body in the manner previously described.

The cover-feeding means associated with this machine forms the subject matter of a separate application Serial No. 757,818 filet December 24, 199A.
